Abstract:

Walnut protein was hydrolyzed with alcalase to produce walnut peptide taking degree of hydrolysis (DH) to indicate reaction degree. The results showed that the optimum hydrolysis temperature, pH, substrate concentration, enzyme concentration and time are 55 ℃, 9.0, 8.0%, 6% and 2 h, respectively. Under the above conditions, the DH is up to 76.16%.

Key words: alcalase, walnut, active peptide
